Let's divide 988737 by 99
The aim is to understand the frequency of 99 in 988737.

Step 1:
If we divide 9 by 99, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 99

Let's proceed to step 2:
The number 99 fits into 98 0 times, leaving a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 99

Going ahead to step 3:
99 can be fit into 988 9 times, resulting in a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 891 from 988 and we're left with 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 99

Step 4:
99 goes into 977 9 times with a remainder of 86.
The next digit of our result is 9. 
Result so far: 99.0
If we take 891 away from 977, we end up with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 99

Moving on to step 5:
When dividing 863 by 99, we get 8 with a remainder of 71.
The next digit of our result is 8. 
Result so far: 998.0
Deduct 792 from 863 and we're left with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 99

Step 6:
The number 99 fits into 717 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 9987.0
If we take 693 away from 717, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
240 divided by 99 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 9987.2
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
99 can be fit into 420 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 9987.24
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9987.242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
99 goes into 420 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9987.2424
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 99, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9987.24242
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
The number 99 fits into 420 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 9987.242424
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 99, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9987.2424242
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
99 goes into 420 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 9987.24242424
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 9987.24242424, with a leftover of 2.4e-08.
